Annam (referred to in Vietnamese as Trung Kỳ) is a region of central Vietnam originally ruled by the Nguyễn Dynasty. in 1887, it became a part of French Indochina as one of three protectorates with a dual system of French and Vietnamese administration under Emperor Bảo Đại, who ruled as a puppet emperor while residing in Huế. In 1948, the protectorate was merged in the Provisional Central Government of Vietnam, which was replaced the next year by the newly established State of Vietnam. The region was divided between communist North Vietnam and anti-communist South Vietnam under the terms of the Geneva Accords of 1954, after the end of French colonial rule.
